Research interests

Research on species interaction networks has identified universal patterns in the way species interact across different habitat types and their consequences for community dynamics and stability. However, most suggested processes responsible for observed structural patterns in ecological networks operate on a local-scale, as those related with consumer-resource dynamics, habitat occupancy or foraging strategies of species. The study of the influence of processes operating at larger scales (e.g. regional and geographical scales) on species interaction network structure and dynamics is still in its infancy.

A fundamental knowledge gap exists on how spatial and biogeographical processes affect species interaction networks structure (i.e. whether and how species network structure varies from local to regional scales and across environmental gradients) and on its consequences for stability, and how this, in turn, affects species distribution and biodiversity patterns. The integration of both biogeographical and spatial processes into the study of species interactions is, thus, a necessary step to understand the sources of variation of species network structure and predict how it would vary as spatial structure or climate are increasingly modified.

My general objective is to integrate spatial and biogeographical processes into species interaction networks research to progress towards a more comprehensive approach that helps us to better predict future scenarios of global change in terms of community structure and stability and, in turn, species distribution.
